  NVDEC: Fix handling of stream changes

- the NVDEC decoder would fail if the stream resolution increased
- as a workaroud, allocate our 'own' frames context - which for some
reason the decoder is happy to release at the correct times and the
decoder continues without issue
- as a side effect, we now need to treat nvdec like VAAPI and VDPAU
(which also use an allocated frames context) and release the pause frame
when seeking/flushing.

  NVDEC: Improve hardware frame context handling

- retain a reference to the created frames context and re-use it if
possible.
- works around streams that trigger a get_format call for each sequence;
but is probably a better solution regardless
